What details would you like? The EMP stuff I have is simply fantastic, it plays extremely loud with no noticable(to me) dip in SQ. The sub is plenty good for apartment's like mine, I could never bring my svs sub home from the office for fear of my neighbors chasing me with torches. Its just a very very good bang for the buck system that has yet to displease me, and I'm sure it wont for any forseeable future. The office 2.1 is where I could really get some serious stereo audio without fear of neighbors. These bookshelves can play at insane volume levels and still sound crystal clear, the tube amp is very cool, and pairing it with an extremely capable sub was icing on the cake. I am very pleased with my purchases.
